Driverless cars

Automakers have recently accelerated their efforts to manufacture vehicles that drive themselves.

TechKnow explores how the latest scientific discoveries around the globe are changing our lives.

The realities of war have made a mark on the minds of many veterans, and can linger long after a deployment has ended. Post-Traumatic Stress Disorder (PTSD) was first diagnosed in 1980, but has been suffered by warriors for as long as there has been war.

Imagine a future where you can just hop in your car, fall asleep and it drives you to work.

At Marine Corps Camp Lejeune, the US military is looking at creative and innovative means to apply technology to combat this problem.

On this week's episode, Lindsay Moran delves into the issue of science vs. PTSD, exploring alternative forms of therapy for veterans diagnosed with the disorder.

Hyperbaric treatment at Camp Lejeune and virtual reality therapy at the University of Southern California's Institute for Creative Technologies are two of the latest.

Elsewhere, Kosta Grammatis gets behind the wheel of the future, testing driverless vehicles that are taking a giant leap from the lab to the road.

Automakers have recently accelerated their efforts to fast track production of these cars.

Grammatis meets Japanese engineer Tetsuya Iijima who introduces him to the main pieces of equipment that turn an ordinary Nissan LEAF into an autonomous vehicle.

They explore the technology behind these cars, and how the vehicle and driver experience may change in the future.
